i'm working on a 04.5 dodge and the throttle is sticking if you accellerate and get out around 45mph and will not stop until you put it in neutral.it has a mp8 with smarty.changed injectors,injector tubes,checked cp3 accuator, rail sensor ,and it still runs away.after changing injectors pulled smarty off ang run away quit,but before changing injectors i tried this and it stayed the same.does anybody have any ideas?
